Specification of Letters Patent.

TYPE-WRITING Macrame.

consists in certain featuresof construction.

and combinations and arrangements of parts, all of which will befully set forth herein and particularly pointed out in the claims. i J I My invention is illustrated in the accompanying drawings in which-- Figure 1 is a side elevation of a type bar and hunger and some of the associated parts of a typewriting machine, the segmental support for the type bars being shown in section. Fig. 2 is a fragmentary front elevation of a section of the type bar segment with a hanger secured thereto and having my invention embodied therein. Fig. 3 is a section of the hanger on the line mm of F ig. -l and'looking in the direction of the arrow at said line. Fig. l is an isometric view of a stiffener or tie-plate and sleeve. Fig. 5 is a side elevation showing a modification of my invention. Fig. 6 is an isometric view of a tie-plate embodying a second. modification. 7

All of the figures ofthe drawing are on an enlarged scale.

In the dra'wings,my invention is shown applied to a type bar hangcrof the Monarch typewriter. Ihis is a front-strike machine having a platenindicated at 1 and having "type bars 2 adapted to strike against the front face-of said platen. Said type bars are supported on a vertical segment 8 by means of long hangers 4 and shorter hangers :"i secured to the front face of the segment 3 by screws 6 which take into threaded holes 7 in the segment. It'will be noted in Fig. 1 that'said -segment is made with two steps, the shorter hangers 5 being secured to the face of the inner step, and the longer hangers e bei-ng secured'to the face of the outer Patentcdoct. 27,1914; Application filedJuly 6,1912. Serial No. 707,963. v

art. The short hangers 5 consist of simple loops of sheet metal having bearings 8 therein, each hanger thus being bifurcated or U- shaped and supporting a typebar pivoted thereto in the manner well-known in the aria. Thelonger hangers-arc also forked and-I are made of -strlps of sheet metal bent up ,intoth'e form best shown in Fig. 3 and-com: prising arms connected together. at one end iby thebend 4 in said strip of metal, and; between the free ends of which the trans- ;verse type-bar pivot 10 is supported in the;

Ebearing openings 11. The two arms or branches of this hanger are secured to gether by a cross-connecting device which ishere shown as consisting of a rivet 12, and between said rivet and the screw 6 said arms orbranches are formed with inwardly directed curves 13 to give access to the, screws 6 of the shorter hangers 5. The particular one of said shorterhangers shown in Fig. 1,

has its screw 6 threaded into the hole-marked 7* in Fig; 2-, and it will be'seen that this screw; would be inaccessible on account of. the long hanger 5 if it were notfor thiscurve 13 in said long hanger.

It has been found in practice that type bar hangers in general, and-the long hangers in particular, are subject to a certain amount of flexure especially under the violent jerks with which type bars'are operated. This gives rise to more-or less vibration of the type'bar, resulting in more or less imperfect;

alinement. -The amount of this vibration is, of course, greater in comparatively long hangers than it is in comparatively short ones, and it is also greater, other things being equal, where the branches are curved or formed with a neck as at 18. The U-shaped hangers of other typewriting machines also have bends in them, not of theprecise forms of the bends 13 but of such character as to It is one of the objects of my invention to stiffen the hanger against'the lateral vibration referred to.

adjusted to the-pivots 10 In most of these sheetmetal hangers the bearin s 8 and .ll are y upsetting the make the said hangers somewhat less stiff 3 than they wouldbe if-they were straighti;

rivets. 12 to a greater or less extent. Said".

rivets are headed up hy repeatediiblows drawing the hanger arms together until said hanger arms and the'bearings 11 are nicely adjusted to the type bar pivots, 'ving just the right degree of closeness of 't to cause.

the type bar. to move with precision but not to be tight and hard to operate. This method of adjustment has heretofore involved rather a nice operation and the result of the riveting has not always been as good as could be desired. The last blow of the hammer that brings the hanger arms to exactly the right distance apart, sometimes raises on the head of the rivet a single bump or high spot which is the only point in the head of the rivet that quite bears against the counter-sunk hanger arm. This hanger arm thus having but a point bearing on the rivet, that particular point when the machine is put into use soon WOI'kSOl beds' itself into the hanger arm or else is itself flattened out by the hanger arm, allowing the hanger arms to spring apart very slightly but still enough to result in a perceptible looseness of the type bar pivot. "By my invention the hanger is improved in respect to both of the matters above described.

I add to the hanger what may be termed a sleeve and tie-plate 14 illustrated separately in Fig. 4. This, in the 'form here shown, consists of a strip, shank or stem of sheet metal which at one end is bent to form a sleeve 15 which surrounds the rivet 12 as shown in Figs. 1 and 3. From the-sleeve portion 15 said plate has an inclined section or ton ue 16, Fig. 1,'extending down ward' and forward to the ward face of the hanger. tion 16 lies between the forks of the hanger to resist lateral fiexure thereof. The lower end 17 of theplate lies fiat across the forward edges of the hanger as shown in Fig. 1, the hanger being applied edgewise upon the segment, and the plate substantially parallel with the plane of said segment or support. In order to. avoid interference with the screws 6 of the shorter hangers 5, the plate 14 is formed with the .cnt-outs 18 substantially corresponding with the curved'parts 13 of the hanger. The part 17 of said plate is formed with a hole 20' preferably somewhat elongated, for the, passageof the screw 6, by means of which the tie-plate is anchored at the securing end. or root of the hanger. p

The sleeve portion 15 is made of such length across the hanger that the rivet 12 can-be, headed up fully, drawing the hanger arms down firmly against the ends of the said sleeve. With this sleeve in place a much more thorough job of riveting can be done without drawing the hanger arms too game of the forclose together and after said riveting has .art of this secand'the sleeve improves the rivet connec-' tions in the hanger arms, and also makes the operation of riveting a .much simpler and far less delicate one. When the hanger secured 'to' the segment as shown in Figs. 1 and 210; means of the screw 6, the head of said screw also binds or clamps the tie-plate firmly upon the hanger and it will be seen that the supplemental tie-plate or device makes said hanger .lar more rigid in a rightand left-haud dirw-tion. -Forces acting in that direction on the hanger itself act on the metal of said hanger across-its thin section Wl'iereas such :Forces act on the tie-plate edgewise in which direction said tie-plate is very rigid. hanger in a direction parallel with that of the retaining screw 6, acting as a washer between the hanger arms and the head of the screw and thus enabling the hanger to he morefirmly secured to the segment.

In the Monarch typewriter each type bar is'provided with a restoring spring 21 connected atone end to the type bar and atthe other end to a fixed'point associated with the type bar hanger. In the machine as at present manufactured these springs are connected to washers 22, which washers are constructedas shown in Fig. 2: with an oil'- setarin 23 and two holes 24:, one for the spring of the type bar that is mounted in The tie-plate also stiffens the the long hanger and the other for the spring v of thattype bar which is mounted in the, .short hanger 5, next. and adjacentto the particular hanger 4 under consideration.

In Fig. 2 it will be seen that'the outer one of the two holes 24 is in line with the screw hole 7 in the segment. I prefer to retain this washer 22. for the sake of connecting the springs thereto.

The tie-plate 14 is adapted itself to act as a washer as far as proper cotiperation with the head of the screw- 6 is concerned. This being true the washer 22 maybe omitted if desired and-the tie-plate 14 shown in Fig. 6 may be employed, said tie-plate being formed with an arm 25 bent backupon itself and having therein two holes 26 corresponding in posi-v tion to the two holes 24 in Fig. 2.

A still further modification is shown in.

Fig. 5 where the hanger 4 issecured to the segment 3 by a screw 6 as before, the head of said screw cotiperating with a washer 22 likethat of Figs. 1 and 2. The tie-'plate14i has the eneral 'characteristicsof the tie ut instead of coming toward the front of the machine and lylng across the" plate 14:

front of-the bifurcated hanger it is introduced at the back of said hanger between the same and the segment 3. In some .situ-.. ations this form of tie-plate may be preferable to thatof Fig. l. -Various changes maybe made. without de-.

parting from the spirit and scope of my invention.
